Laub, 4920 Marine Drive, Chicago, Ill. 60640 Filed Aug. 21, 1969, Ser. No. 852,045 Int. Cl. A43d 3/00 U.S. Cl. 12123 Claims ABSTRACT OF THE DISCLOSURE A protective shell comprises an integral plastic member adapted to fit over a peg rack for holding shoe uppers during the sole cementing operation. A conventional peg rack comprises a bar having a plurality of longitudinally spaced pegs, which may be called pins or paddles, extending from one side thereof in approximately perpendicular relationship to the bar. The plastic member includes an annular ledge adapted to fit over the top surface of transverse bar of the peg rack, and a plurality of arms projecting forwardly from the ledge and adapted to fit over the pegs. The arms are spaced to receive a shoe upper between adjacent arms and each arm has downwardly inclined side walls to support a last on which a shoe upper is mounted and to provide nonscuif engagement with the shoe uppers.

This invention relates to a protective Shell for a peg rack adapted to hold shoe uppers during the sole cementing operation, and is particularly concerned with a shell that may be easily engaged with or disengaged from the peg rack.

In the manufacture of shoes it is customary to hold a plurality of shoe uppers on lasts between adjacent pegs of a peg rack as the soles are cemented to the inturned bottom edges of the shoe uppers which are held in inverted position. The pegs, which are usually wood, must be frequently cleaned because of the adhesive that adheres to them. The production of shoes is reduced considerably by the amount of time required for cleaning the racks. Another disadvantage of the wood pegs is that the wood surface often becomes rough and scuffs the surface of the uppers in contact therewith.

The protective shell of the present invention completely covers the wood pegs so that the adhesive cannot soil them. Whenever any adhesive soils the surface of the plastic shell the loss of production time is minimized because the shell is removed from the rack and is immediately replaced by a clean shell. The dirty shell may then be Washed without further loss of production time, and thus made ready to replace a subsequently dirtied shell.

Suitable structure by means of which the above mentioned and other advantages of the invention are attained is fully described in the following specification, taken in conjunction with the accompanying drawings showing two preferred embodiments of the invention, in which:

FIG. 1 is a fragmentary perspective view of a protective shell embodying the invention and a peg rack over which it is adapted to fit;

FIG. 2 is a fragmentary bottom plan view of the shell mounted on the peg rack;

FIG. 3 is a cross sectional view, taken in the plane indicated by the line 33 of FIG. 2;

FIG. 4 is a view, similar to FIG. 1, showing another embodiment of the invention;

FIG. 5 is a bottom plan view of the structure of FIG. 4, with the protective shell mounted on the peg rack; and

FIG. 6 is a cross sectional view, takenin the plane indicated by the line 66 of FIG. 5.

Referring to FIGS. 1 to 3 of the drawings, the peg rack, which is conventional, comprises a transverse wooden bar 11 and a plurality of wooden pegs 12 projecting forwardly from the transverse bar. Each peg has a flat bottom 13 that is secured at a point intermediate the length of the bar to a brace 14 that extends parallel to the bar 11 and is secured at each end to a side wall 15 extending forwardly from the bar at each end thereof. The sides of each peg slope outwardly from the top of the peg to provide inclined surfaces for the reception of shoe uppers between adjacent pegs. The transverse bar may be of any desirable length to hold pegs for supporting six or twelve shoe uppers. The adjacent pegs are so spaced that the inclined surfaces of adjacent pegs support a shoe upper mounted on an inverted last.

The protective shell for protecting the peg rack from an accumulation of adhesive is preferably formed from a flat sheet of any suitable thermoplastic material, such as polyethylene, polypropylene, or polystyrene, for example, but may be molded into shape if desired. The shell comprises a plurality of arms 16 and 17 projecting forwardly from the front edge of an angular ledge 18. The ledge 18 is shaped to cover the top surface and the portion of the front surface of the bar 11 that would otherwise be exposed to the adhesive that is used to cement soles to shoe uppers mounted on lasts supported in inverted position between adjacent arms. The arms 16 are each dimensioned to fit over single pegs, but the arms 17 are wide enough to fit over a pair of pegs. The arms, regardless of their respective widths, are spaced apart to re ceive shoe lasts between adjacent arms.

Each arm, except the two arms at the outer ends of the shell, has a pair of depending side walls 19 sloping outwardly from the top of the arm to provide smooth inclined surfaces converging downwardly to support lasts of different Widths. Each end wall has a depending side Wall 19 on its inner side, and on its outer side has a wall 20 shaped to fit over the surface of the side wall 15 of the rack that would otherwise be exposed to the adhesive. The outer side walls 15 of the outermost arms serve also to reinforce the shell. The shell is preferably provided with additional reinforcement in the form of an integral transverse channel 21 traversing the spaces between adjacent arms. The channel 21 fits over the top and sides of the brace 14 to protect it from the adhesive. The extra strength of the shell provided by the channel 21 is desirable because the shell is designed for use with mans shoes, and the size of the shoes, as compared to womens and childrens shoes, makes it necessary to use a comparatively large shell.

The arms 16 and 17, the ledge 18, and the channel 21 are all free of any bottom wall structure. This structure permits the shell to be dropped in place over the top surface of the rack and to be easily removed therefrom whenever any adhesive that might mar the shoe upper accumulates on the exposed surface of the shell. When one shell is removed it is replaced by a clean shell and is washed to remove the adhesive therefrom.

The embodiment of the invention shown in FIGS. 4 to 6 of the drawings is designed for use in cementing soles to the uppers of womens and childrens shoes. The difference in the size of the shoes permits omission of the channel 21 from the shell of FIGS. 4 to 6.

In FIGS. 4 to 6 the peg rack comprises a transverse bar 22 from the front edge of which a plurality of pegs 23 project. The pegs 23 are arranged in pairs, and the pegs of each pair are directed at diverging angles forwardly from the bar 22.

The protective shell comprises a plurality of arms 24 projecting forwardly from an angular ledge 25 with which the arms are integral. The ledge is shaped to cover the top and front surfaces of the transverse bar 22, and each arm 24 is shaped to cover the top and sides of two diverging pegs 23 except at each end of the transverse bar. A single peg 23 at each end of the transverse bar cooperates with the adjacent pair of pegs to provide a space adapted to receive an inverted last on which a shoe upper is mounted.

Each arm 24 has a pair of depending side walls 26 that slope outwardly from the top of the arm. The arms 24 are less rigid than the arms of the embodiment of FIGS. 1 to 3. Each arm 24 has a depending end wall 27 that is curled inwardly at its lower edge to facilitate securement of the shell to the peg rack. The shell has suflicient flexibility so that after the rear portion of the shell is secured in place about the transverse bar 22, each arm 24 can be snapped downwardly over the outer ends of a pair of pegs 23. The end walls 27 extends inwardly a sufficient distance to prevent accidental displacement of the arms, but the arms may be removed easily by stretching them slightly in the longitudinal direction.

Although I have described two preferred embodimnts of my invention in considerable detail, it will be understood that the description is intended to be illustrative, rather than restrictive, as many details of structure may be modified or changed wihout departing from the spirit or scope of my invention. Accordingly, I do not desire to be restricted to the exact structure described.

I claim:

1. A protective shell for a peg rack comprising a transverse bar and a plurality of pegs projecting forwardly from said bar in a common plane, said shell comprising a plurality of arms adapted to cover the top surfaces of said pegs, and an angular ledge integral with said arms at the rear ends thereof, said ledge being adapted to cover the top surface of said bar, said arms being spaced longitudinally of said ledge to receive and support shoe uppers between adjacent arms.

CPI
